Kustolf is a mysterious toa who has had a bad life. He has had to kill to survive, and never trusts anyone even if they're his friends. How he became a toa is a mystery, but when he did he became a killer-for-hire and was often hired by the Dark Hunters on missions.

The OoMN had seen Kustolf's skills in killing demonstrated on many people, and eventually decided they'd had enough of it. Jordan 2444 led a mission to kill Kustolf, but when he continued to fight when he knew he couldn't win, Jordan took a liking to him. He soon asked Kustolf if he would join the OoMN as a sniper and use his ways on some of the monsters who deserved capital punishment. Kustolf said yes.

Now that Jordan has been sent as a secret agent on Spherus Magna, Kustolf and some other members are joining him. They're goal is to disband the Rogue and take Magmagear captive. And one more thing: They need Callan and Davix's help.

Callan: Hey Phos, I FINALLY MADE KUSTOLF!!! :D
Phosphorus: After all this time?!?! NO FORGIVENESS!!! Take him out, Kustolf!
Callan: Aw, CRAP!!!
Guess who got revamped? Hint: You don't need one.
Later guys!!
